I think Retailers are taking a Wait and See Approach to e-Cigs.
Right now, e-Cigs are sort of in the “Wild West” phase. Untested, Unregulated and Untaxed.
There are Bans purposed in Many Municipalities and even some States. There is also things in the works with the FDA which could Drastically Alter the e-cig Landscape at the Federal Level.
And of course, there is also the Potential Risk, as it seems with ANYTHING in the US, that someone will bring a Hundred Billion Dollar Lawsuit against Retailers claiming that e-Cigs harmed them.
Many people in Business will tell you that selling a Product that is intended for Human Consumption that is Not Regulated is a Very Risky. And if you do, you better have Big Time Liability Insurance and the Legal Will to fend off all comes.
So when put together, I think many Retailers are Leery of Jumping into e-Cigs at this time.
